See the appendix for definitions and details of their calculation from the observational data. Here again the range of vertical wavelengths considered in the variance integrals is from 130 to 320 m. Patterns are generally qualitatively similar for other ranges of suitable vertical wavelengths as well, however, Rω (and in particular the strain variance) is very sensitive to the wavelength limits of integration.
